Show HN: FadNote – Zero-knowledge secret sharing for your CLI and AI workflows

Hi HN,

I built FadNote because I realized that while services like Privnote or Yopass exist, they often feel like an "interruption" to a developer's flow. You have to leave your terminal, open a browser, paste, and copy again.

FadNote is designed for integration, not just web-visiting. The goal is to provide a zero-knowledge "utility layer" that lives where you already work:

OpenClaw Skill: For AI-powered workflow automation.

CLI First: A zero-dependency Node.js script to pipe secrets directly from your terminal (echo "secret" | fadnote).

Obsidian Plugin (In Dev): To share snippets directly from your knowledge base.

The Security Model (Trust-less):

Local Encryption: Secrets are encrypted via AES-256-GCM with 600,000 PBKDF2 iterations before they leave your machine.

The URL Fragment: The decryption key is stored in the URL fragment (#key). Since browsers never send fragments to the server, I literally cannot read your data even if I wanted to.

One-Time & Faded: The encrypted blob is deleted from the server immediately after the first read or after the TTL expires.

Why I’m posting here: I’ve integrated this into OpenClaw and am finishing the Obsidian plugin. However, I’m looking for feedback on where this "fading note" utility belongs next.

The real question for you: Aside from IDEs (VS Code) or CI/CD pipelines, where else should I integrate this to make sharing temporary secrets frictionless in a professional workflow?

I’m eager to hear your thoughts on both the crypto implementation and the next integration targets!
